Refer to Statement B under Testing Information at http://www.aruplab.com.
Note: "Not detected" PCR screening results should be terminally analyzed by restriction fragment Southern blot hybridization (RF-SBH) to definitively exclude T-cell monoclonality.  This is not automatically performed unless otherwise stipulated and can be performed using fresh or frozen tissue.

For confirmation testing refer to T-Cell Clonality Assessment by Restriction Fragment Southern Blot Hybridization, Tissue (0055594).
CPT Code(s): 83907 Lysis; 83891 Isolation; 83898 x4 Amplification; 83896 x3 Nucleic Acid Probes; 83909 x4 Capillary electrophoresis; 83912 Interpretation and report - Additional CPT code modifiers may be required for procedures performed to test for oncologic or inherited disorders.
